TYPE-WRITIN G MACHINE.

T o all whom t may concern.'

Be it known that I, GEORGE A. SEIB, citizen of the United States, and resident of Ilion, in the county of Herkimer and State of New York, havel invented certain neW and useful Improvements in Type-Writing Machines, of which the following is a speciication.

My invention relates to typewriting machines and more especially to dead key mechanisms for such machines. The invention has for its principal object to provide cer-` tain improvements in the means for writing those characters which are .sometimes designated bythe general term accents.

To the above and other'ends which Will hereinafter appear, my invention consists in certain features of construction and combinations and arrangements of parts, all of which will be fully set forth herein and particularly pointed out in the claims.

In the accompanying drawings,

Figure 1 is a right-hand side elevation v with the right-hand parts of the frame sectioned away and showing as much of the typewriting machine as is necessary to illustrate my invention.

Fig. 2 is a fragmentary rear'elevation of a portion of the mechanism.

Fig. 3 is a view in section on the line 1fof Fig. 2, and looking in the direction of the arrows at said line.

Fig. 4 is a diagrammatic plan. view of the extreme right-hand side of the keyboard together with the corresponding type bars,

said type bars being shown in developedv position.

Fig. 5 is a fragmentary perspective view of one end of the universal bar which operates the escapement.

The ,main frame of the typewriter to which I have shown my invention applied comprises a--base part 1, corner posts 2, and a top plate 3. The top plate 3 has the general form of that of the Remington No. 10 typewriter, and said machine has a carriage which is similar to and may be identical with vthat of the Remington No. 10.

The carriage is notshown, but the platen 4 lis indicated in Fig. l, and the said carriage has afeed rack 5, which coperates with a feed pinion 6 mounted on a shaft which at its-rearend has an escapexnent wheel 7 controlledby feed dogs 8 mounted on a dog Specification of Letters Patent.

dle of the carriage and adapted to travel onv a shift rail 12, which is supported by vertical arms 13, one near each end thereof. y

Said arms 13 are made of sheet metal, and each of theml at its lower part is bentolf into a fore-and-aft plane, as shown in Fig. l, and the lower end of said arm is pivoted at y14 to a shift key lever 15, there being one of these levers on each side of the machine. Said levers 15 are freely pivoted on a cross rod 16 in the base of the machine, and each of them is fastened by rivets 17 to a heavy cross piece 18, the function ofsaid cross piece being to cause the two levers 15 to rock in unison. Each of said levers 15 extends into the keyboard where itcarries a shift key 20, Fig. 4.

The type bars 21 are guided at their heels in radial slots 22 cut ina type bar segment 23, and said type bars are pivoted'on a wire 24 lying in a slot in the said segment. y

Theftype bars are operated by sub-levers 25 having the form of bell cranks which are-pivoted on a wire 26 and are guided in .slots cut in a cross bar 27 in the base ofthe machine. Each of said sub-levers 'has a pin 28 at its upper end that plays in a slot in the heel of the type bar. The bell cranks 25 are connected by links 30v with printing key levers 31 which are pivoted at 32 and are provided with returning springs 33 and with but-tons or printing keys 34.

A type bar center-guide 35 is secured to i extension of the bracket 51.V

ends, said universal bar has two arms 39 projecting therefrom toward the rear, and

'each of said arms is pivoted at its rear end to the upper end of an arm 40 projecting from a transverse rock shaft 41 which is journaled in brackets 42 depending from the top plate 3. Said rock shaft has a third arm in the middle of the machine which opei'atesa push link 43 which vat its rear end is connected with the lower arm 44 of the escapeinent dog rocker. Said dog rocker has a restoring spring 45 which draws the arm 44, link 43,- and universal bar 37 toward the front ofthe machine. This entire construction of universal bar and escapeinent mechanism and the connections from said universal bar to said escapeinent mecha` nism can be of any suitable construction but with a, certain exception whichwill be described in detail hereinafter, they are here shown like that set fort-h in my prior application Serial No. 118,607 hereinbefore referred to.

The ribbon vibrating mechanism is' not here shown in all its details, as itis in most respects substantially like that shown and described in my prior Patent No. 1,203,795, dated November 7, 1'916. Said mechanism comprises a vibrator 46 which is guided on a `bracket 47 extending upward andtoward the front from-ashiftable frame 48. Said frame is imountedv on parallel links49 and 50, which links are pivoted in a depending bracket 51 secured to the under side of the top plate 3. TheA frame 48 is drawn upward vby a spring 52'and its upward motion is limited by a wheel or roller which is mounted in said frame 48 and which bears against the under side of a rail 54` mounted on the cross bar 10 of the shiftable platen frame. vibi'ator frame 48shifts upand down with the platen frame.

The vibrator 46 isl mounted on the forward end of a horizontal arm 55 of a bell crank which isipivoted atf56 in the fraine 48, and which has a depending arm 57 which is operatively connected by means not shown herein but which are fully se't forth in my is pivoted at 00 to a downward and .forward In my said prior patent this lever is shown pivted to the type bail segment. As fully set forth in my said prior patent, the leverr 58 is in the nature of a four-sided frame having two vertical lever arms spaced apart and at their upperends connected by a rectangular head 59, which, in said patent, is designated by reference numeral 70. i Said vrectangular head is operatively connected with the bell crank arm 57 by means `of two levers and links which are fully shown and described in my said prior patent but which have been The construction is such that the omitted from the present drawings to avoid unnecessary complication. The two spaced branches of the leverffran'ie 58 are connected together at their lower ends by across rod 61, which in said patent is operatively connected with the key-lever operated universal bar of the machine. Said cross bar is'in the present machine also connected with a universal bar 62, which lies beneath the printing key levers, each of which is formed with a lug `63 adapted to operate said universal bar. .The bar 02 is supported by arms 64 promoved toward the rear and the vibrator will be thrown up to printing position, the extent of its throw depending on certain adjustments which are not brought out in the present case but are fully vset forth in my said priorpatent.

The universal bar 62 which controls the vribbon vibrator is operated at every key stroke and it will be perceived that in order to makeV any key a dead key it is only necessary to constructthe parts in such a way that the type bar which is operated by that key shall not operate thel curved universal bar 37 which controls the escapement.

In the present instanceI have shown five special keys 34, each of .which is adapted to print an ordinary character requiring a letter space movement of the carriage when the case shift'mechanism is in lower case position and is adapted to print an accent type,

or character not requiring letter spacing of the carriage', when the case shift mechanism is in upper case positionA` and said five keys are the five right-hand keys in the keyboard; but the number of such keys can be .varied and their disposition can be varied to a certain extent. prior Patent No. 1,203,795, to the upper end .of a lever 58 ofthe first order, which lever Iii order to provide. for preventing these keys 4from operating the type-bar operated universal bar 37 when writing an upper case character, the right-hand end of said univer` sal bar is formed with a notch or cut-o ut 68Fig. 5, of en evtent lengthwise of th universal blar `sufiicient to clear the heels o terponent is provided (consisting of a segall of the tive type bars connected with saidk i mental piece 70, Figs. l, 2 and 3, said interponent lying in part fiat against the rear face of the type bar segment 23 and being pivoted on a long screw 7l screwed into said segment from behind, said interponent being thus mounted for oscillatory moveand under certain conditions to cause thespecial type bars to operate the universal bar 37 through the instrumentality of said interponent. Said interponent 70 has the form of a comb plate having a series of four slots 74 'having ka spacing corresponding with the four-right-hand slots 22 in the segment 23. The interponent normally stands in the position shown in Fig. 2 where each of the slots 74 is between two of the slots 22 and the solid parts of the interponent between its slots 22 cover the last five slots in the type bar segment. In this position of the parts, if any one of the special type bars be operated it will strike the interponent and push it toward the rear with a. sliding bodily movement against the universal bail 37, thus causing an operation of said universal bar and a stepping ofthe carriage. If, however, said interponent be swung a suitable distance u ward about its pivot 7l each of the slotsu 4 will register with one of the slots 22 and the fifth slot22 (from the top, F ig. 2) will be uncovered by the shifting of the interponent. If in this position of the parts any one of the last four type bars be operated the heel thereof will pass idly into one of the slots 74 and will not move the interponent nor the uni-v versal bar 37 toward the rear; and if the fifth type bar be operated its heel will pass beneath the interponent and will not operate the universal bar.

In order to shift the interponent 70 when the platen is moved to upper case position, a` lever 75 is pivoted onthe screw 1. which screw is prolonged toward the rear to accommodate said lever and' to accommodate also a compression spring 76 coiled about said screw and compressed between the lever and the interponent 70. This spring presses said lever up against the head of the screw and also presses the interponent toward the segment 2 3.' A pin 77, projecting rearward from the interponent, passes loosely through a hole in the lever' 75 so that if said lever be rockedv the said inter- A"ponent will also be rocked in unison therewith, at the same time leaving said interponent free to be moved bodily toward the rear by the type bars. The lever 7 5 extends downward and toward the operators right and at its free end it has a small wheel 78 journaled thereon, said wheel resting on the upper surface of a shelf-like bracket 80 which bracket is secured by means of a screw 8l to the right-hand arm 13 of the case shift frame. r1`he bracket 8 0 is made of sheet metal with a horizontalshelf on which the wheel 78 rides and a vertical part which lies against the arm 13; and said vertical part is formed with an upright slot 82 through which the screw 81 passes to allow of an up and down adjustment of the bracket. It will be understood that this bracket will be adjusted to such a height as that when the parts are in. upper case posil tion the slots 74 will register correctly with the slots 22.

The arm 75 is positively moved .upward when the case shift key is depressed, but it is restored to normal position by yielding means. Said arm or lever is drawn downward in order normally to hold the wheel 78 on the shelf 80, by means of a spring 83 which at its upper end is connected with said arm and at its lower end is connected with a branch 84 ofthe bracket 80, The tension of this spring changes but slightly in the ordinary operation of the parts but the spring has markedadvantages over a positive connection for the following reason: If after writing an accent, which will be done with one of the five special type bars when the parts are'in upper case position, the operator should let go of the shift key before the type `bar had got out of the slot 74, the interponent 7 0 would tend to return to its normal position shown in Fig. 2 before said type bar had got out of the slot and there would be a tendency to bind the type bar in the slot and thus preventV it from returning to normal position, and there would also be a severe strain on the'parts if the interponent 70 were posi tively returned to normal position by the case shift mechanism, which mechanism is heavy. rlhe use of the spring 83 to return said interponent renders such a situation as that just referred to harmless. If the shift key is released before the type bar passes out of slot 74, the case shift mechanism'lwil'l return to lnormal position and 'the interpone'nt 70 will remain in its shifted position until the type bar has passed out of the slot 74, and the friction .on the type bar will be only that caused by the tension of the spring and b the weight of the interponent 70 and lever 5. This friction is not enough to prevent the return of the type bar. As soon as the type bar escapes from the slot 74 the spring and the weight of the parts will return the interponentfto its normal position.

It will be understood that if the described mechanism is embodied in a segment-shift machine, the part corresponding to the shelf 80 will be on a fixed part of such machine.

' With the mechanism thus' far described it will be perceived that all of the five righthand printing keys and type bars can be made dead in the upper case 'position or that any combination of. said five type bars can be rendered dead. If a smaller number than the whole five was 'needed only enough slotsl 74 would be cut to accommodate the typel bars'it was desired to make dead. ,If the fifth type bar from the end was desired to be made alive in both case positions the interponent 70, would be prolonged to a slight extent on its lower side so that the fifth slot would not be uncovered when the 'interponent was shifted. It will also be perceived that an interponent of this character could be put into other parts of the segment ifdesired, though accent keys are usually situated at the extreme right-hand side of the keyboard.

It will also be perceived that if such a thing be desired for any reason, the type bars can be made alive 'for upper case and dead for lower case vby merely cutting the slots 74 in such positions that they register with the slots 22 in lower case instead of in upper case position. It would also be possi-v ble, 4if such a thing was desired for any reason, to make one type bar dead'in upper -case position and alive in lower case posi- `in the same position of the carriage. If a letter is first written the carriage immediately stepsone. space to the left, and in order then to write an accent over said letter said v ac c'ent must be offset one space to the left.

I provide each lof the special or accentwritingtypebars with a special L-sliaped Atype block 85 having a lower case type 86 thereon in the usual position and said type block at its outer end formed with an of'lset 87 having an accent type 88 thereon, said accent type being offset one letter space to the left from the lower case type 86 on the same type block. It will be lnoted that this type bar will be guided'by the part 36 thereof, entering the center guide 35 in the saine Way as an ordinary type bar, and that the lower case type 86 will strike the platen in thel same manner as other lower `case types;

but that if the platen is shifted to upper case position the upper case type will strike one letter space to the left of the ordinary position and over the letter that has justA been written. This offsetting of the upper case type to the left is made possible by the flaring arrangement of the right-hand type bars of'. the system in the basket, a developed View of which is shown in Fig. 4. In this Vparticular part ofthe basket the upper end of each type block projects forward and ,j 4riglitward beyond the upper end of the next type block tothe left'thereof, the type blocks lapping over one another in a.4 sort of staggered or nested arrangement. It will be understood Athat a similar overlapping of offset types in lower case position could be arranged at the left-hand end of the segment if that were desired.4 The arrangement at the right-hand end of the system is'better for two reasons, one being that that is the part of the keyboard where it is customary to put tlieaccent keys, and the other being that most of these accent marks are written over the letters, and the types therefor are 'situated relatively higher on the type blockl than the letters. If it were necessary to write amark of this character under a letter, the left-hand side of the. keyboard might- Y, be the better place to locate such a mark, but

in that event the mark would be a lower c ase cliaracterinstead of an upper case character, as in the present instance.

Various changes can be made in the det-ails of construction and arrangement without departing from my invention.
